The disadvantage is that updates are too slow, too slow.

It has been changed to two points, and it has been ok for a few months without explanation. Although I have updated another chapter recently, I promise that it will be completed. But I can't guarantee whether the author will have a mental breakdown. The plot is pretty good.
It's being serialized, and it looks good, although at the moment it's more like traveling into another world or traveling through a book.

Still give it a 2 points. After the initial novelty, it seems a bit ordinary, and the performance of the 16-year-old protagonist still feels very innocent.
